Hodgkin's lymphoma is affecting young adults and having exhibited a fairly constant frequency over the past few years. Hodgkin's lymphoma in a young adult has a good prognosis, with only approximately 10% of patients dying of disease. Hodgkin's lymphoma in an elderly patient is more difficult to treat. Cytostatic chemotherapy combined with radiotherapy is the treatment of choice. New recommendations involve a reduced volume of radiotherapy. In long-term follow-up, increased numbers of new cancers and cardiovascular disease are found in patients having had Hodgkin's lymphoma as compared with the reference population.
